摘要
利用电磁场和误差分析理论,在阐述天线远场测量条件的基础上,分析了微波暗室有限测试距离对天线远场测量的影响,建立了误差模型,并结合实例说明了微波暗室有限测试距离对天线场强测量、增益测量的影响。分析结论可为实践中快速准确地确定适合在微波暗室内进行测量的天线尺寸和频率范围提供具体的技术指导。
According to the theory of electromagnetic field and the tbeory of error analysis, the far field condition for antenna test is discussed, the influence of limited test distance on antenna far field measurement in a microwave anechoic chamber is analysed, and the error model is established. An example is given to illustrate the influence of limited test distance on antenna electric field intensity and gain measurement in a microwave anechoic chamber. The conclusion can provide practical technical guidance for deciding quickly and accurately the size and frequency range of antennas suitable for being tested in a microwave anechoic chamber.
